I always knew that the intricate designs and logos on NASCAR racers were decals, but I've never actually seen them applied. Interestingly enough, installing a decal on ones car is nowhere near as hard as you would think. As long as you have a clean body and minimal dings/dents, you shouldn't have any trouble at all. You can check out Joe Gibbs Racing here. Take a look at how the pros do it and you will see what I mean.
